Violane
is a violet to light blue, manganese-rich variety
of Diopside. Violane crystals are extremely small, too small
for faceting so Violane gems are only available as cabochons.
These cabochons take a high polish and are very attractive.

is a member of the Pyroxene group of minerals that also
includes Enstatite,
Hypersthene, Jadeite and Spodumene.
